Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500048-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Planar CH₃NH₃PbI₃ perovskite solar cells</bold> with constant 17.2% average power conversion efficiency irrespective of the scan rate are described. These properties are attributed to the formation of a pure CH₃ NH₃ PbI₃ thin film by the introduction of a HI solution. Thereby, charge‐injection/separation efficiency, charge‐collection efficiency, diffusion coefficient, carrier lifetime, and traps are improved. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjrk4h111" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
